Application filed April 20, 1886. Serial No. 199,477. (No model.)

To all whom it may concern.-

Beitknown that I, EMERY RoYoE, a citizen of the United States, and aresident of Palisade, in the county of Minnehaha and Territory ofDakota, have invented certain new and useful Improvements in RotaryPlows or Cultivators; and I do hereby declare that the following is afull, clear, and exact description of the invention, which will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, which form apart of this specification, and in which Figure l is a perspective viewof my improved rotary plow or cultivator. Fig. 2 is a top view of thesame; and Fig. 3 is a 1ongitudinal vertical sectional view of the same.

Similar letters of reference indicate corresponding parts in all thefigures.

My invention has relation to that class of rotary plows or cultivatorsin which one or more shafts are journaled transversely in the forwardend of a frame, pivoted at its rear end within a wheeled frame, andreceiving rotary motion from the drive shaft or aXle having thedrive-wheels, and in which this shaft or shafts are provided withradiating oblique blades, which will spade the soil; and it consists inthe improved construction and combination of parts of the same, ashereinafter more fully described and claimed.

In the accompanying drawings, the letter A indicates a rectangular framehaving transverse bearings 13 B near the rear ends of its side pieces,in which bearings the drive-axle O is journaled, ha ing the drive-wheelsD D secured upon its ends.

A rectangular frame, E, having two longitudinal bars, F F, at itsmiddle, and having these bars, as well as its side pieces, cut away forthe drive-axle, as shown at G, is pivoted at its rear end upon atransverse rod, H, secured at its ends in the rear ends of the sidepieces of the outer wheeled frame, and two short shafts, I I, arejournaled in the forward end of the frame in hearings in the side piecesand in the longitudinal bars. These shafts are square, and havecylinders J J secured sliding upon them, and the cylinders are providedwith a number of radiating arms, K, provided with oblique blades L.Chain-wheels M are secured upon the shafts, and chains N pass over thesewheels and over chain'wheels 0 upon the drive-axle, so that thecylinders, with their blades, may be revolved by the drive axle andwheels.

Levers P P are pivoted at their rear ends to the rear end piece of thewheeled frame, (one at each side of the seat Q for the driver,) and theforward ends, R, of these levers are bifurcated and straddle thecylinders, serving to slide them upon the shafts. The rear portions ofthe levers are provided with laterally-projecting arms S S, the innerends of which are formed into stirrups T; and the driver may place hisfeet into these stirrups and move the cultivating-cylinders closer to orfarther away from the row of plants, which is straddled by the machine.

A rope or chain, U, is secured at one end to the forward end of thehinged or pivoted frame, and passes over a pulley, V, upon the forwardend piece of the wheeled frame, and the rear end of this chain issecured to a lever, W, which is pivoted upon the rear end piece of thewheeled frame and provided with means for adjusting it, so that thepivoted frame may be raised or lowered by means of this lever,

raising or lowering the cultivating-cylinders.

The revolving cylinders,with their arms and blades, will spade and stirup the soil;and the blades are secured obliquely to the ends of thearms, so that they may either throw the soil toward the row of plants orfrom the row of plants, as it may be desired.

The driver may draw the cylinders closer to the row of plants or fartheraway from them, as desired, by moving the levers with his feet in thestirrups, and he may regulate the depth, to which the blades are toenter by means of the'lever lifting the pivoted frame.

Having thus described my invention, I claim and desire to secure byLetters Patent of the United States- 1. In a rotary plow or cultivator,the combination of transverse shafts journaled in the frame and havingmeans for revolving them, cylinders sliding upon the shafts andrevolving with them and provided with radiating arms havingdigging-blades, and levers pivoted at their rear ends at the rear end ofthe frame at both sides of the seat for the driver and having bifurcatedends straddling the cylinders, and having laterally-projecting armsformed with stirrups at their inner ends for the drivers feet, as andfor the purpose shown and set forth.

2. In a rotary plow or cultivator, the combination of a rectangularframe having transverse bearings near the rear end, a drive-axlejournaled in the bearings and having drivewheels at its ends andchain-wheels inside of the bearings, a frame pivoted at its rear end inthe rear end of the wheeled frame, a lever at the rear end of the framehaving a chain passing over a pulley at the forward end of the frame andsecured to the forward end of the pivoted frame, shafts journaled in theforward end of the pivoted frame and provided with chain-wheels havingchains passing over the chain-wheels upon the driveaxle, cylinderssliding upon and turning with the shafts and having a number ofradiating arms provided with oblique blades, and levers pivoted at theirrear ends upon the rear end piece of the wheeled frame at the sides ofthe seat for the driver and provided with inwardly-projecting arms nearthe inner ends, having stirrups for the reception of the feet of thedriver, and provided with bifurcated forward ends straddling thecylinders, as and for the purpose shown and set forth.

In testimony that I claim the foregoing as my own I have hereuntoaffixed my signature in presence of two witnesses.

EMERY ROYCE.
